ANTIPLUG DEVICE FOR TOBACCO PIEES AIJD METHOD OF MAKING THE S AIME.

Application filed March 12, 1925.

The invention relates to improvements in an anti-plug device for tobacco plpes and so that it will readily accommodate itself to bowls of different sizes and so that it can be easily inserted and readily removed from the bowl as occasion demands and such that the article after removal can be easily cleaned.

A further object is to provide a device which can with reasonable care be used in definitely and which can be sold cheaply.

A further object is to provide a method of making the device which allows the article to be made quickly effectively and cheaply.

With the above more important objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawing, in which:

Fig. 1 is an enlarged the device.

Fig. 2 is a top plan view.

Fig. 3 is a vertical sectional view through the bowl of a smoking pipe showing the device therein in side elevation and practically full size.

Figs. 1, 5, 6 and 7 are perspective views showing different steps in the method of manufacture.

Fig. 8 is a side view of the device just prior to it being shaped as shown in Figure 1.

In the drawing like characters of refer ence indicate corresponding parts in the several figures.

As the article can be best understood after the method in which it is manufactured is described, I will first proceed with the dedetailed side view of scription of the method of making the de-- vice. I take a predetermined length of comparatively fine wire 1 and attach one end thereof to the small end of a cone shaped mandrel 2, the mandrel being carried by a shaft 3. One end of the wire is here shown as bent at right angles to the body thereof to provide a right angled hook 4 which enters a receiving opening 5 in the end. of the man' Serial No. aoao.

drel. This forms the fastening. The shaft is then rotated in any suitable manner to form a conical shaped wire coil 6 as best shown in Figure 5. I

After this cone-shaped coil has been made, it is slipped endwise off the mandrel and shaft. 1 then take two straight lengths 7 and 8 of somewhat stouter wire and pass one through the coil and the otherdown the out side thereof as best shown in Figure 6. This being done, the ends of the wire lengths 7 and 8 are caught in any suitable manner and twisted. When initially twisted, they and the coil will take a position somewhat as shown in Figure 7. Upon one, however. continuing to twist the wires 7 and 8 further than as shown in Figure 7 the separate coils of the wire 1 will start to swing around in a spiralling manner, this being brought about by the tightening of the wires 7 and 8.

When the wires 7 and 8 have become fairly tightly twisted together as shown in the enlarged view Figure 8, it will be found that the various coils of the wire 1 are grouped around the twisted wires 7 and 8 in a spiralling manner. I might here remark that when the twisting of the wires 7 and 8 is finally completed. the appearance of the device vari-es considerably and whilst I have shown a particular shape in Figure 8, this might vary as its final shape depends entirely on the amount of twist given the wires 7 and 8.

After the device has been formed as shown in Figure 8, one by holding the twist edwires 7 and 8 can press the coils of the wire 1 in one direction and they will take a neatly nested position and form a screenlike cone 9 as best shown in Figures 1 and 2. the cone being formed from the coils of the wire 1 spiralling around the central wires 7 and 8. The wires 7 and 8 are cut off to approximately the length shown in Figure 1 and they form a stiff central stem 10 carrying the cone-shaped screen. Whilst I have described the forming of one device at a time, it will be readily seen that a number of the coils 6 could be placed on parallel wires 7 and 8 and all made'at the same time by the twisting of the wires 7 and 8 and subsequently it is simply a matter of cutting the wire between the formed cone shaped screens.

When this device is to be used, it is placed in the base of the bowl 11 with the stem 10 vertical. Tillie conashaped screen. can. be

readily compressed or made smaller by squeezing it to permit it to pass easily into the bowl. After the lower end 01 the stem 10 has engaged the bottom of the bowl, one by inserting his finger and pressing down on the screen can spread it out against the wall of the bowl. The device readily accommodates itself to the various interior diameters 01 pipe bowls. hen it is in use, it obviously supports the tobacco 12 so that it cannot plug the entrance to the hole 13 in the pipe stem and prevents the accumulation of saturated tobacco in the base of the bowl. A cool smoke is assured and a tree draft through the stem is maintained.

If it is desired to clean the device, one pulls it out with a hooked wire and. puts it in a flame to burn off any collected material. After burning, the carbon can be shaken oil by tapping the screen.

What I claim as my invention is:

1. An anti-plug device for a smoking pipe comprising a stem formed from two camparatively short stiff wires twisted together and forming a central stem and a screen carried by the stem so formed and made outer side thereof and finally twisting the latter wires to cause the separate coils to take a spiralling position around the twisted wires.

3. The method of making an antiplug device for a tobacco pipe which consists in providing a coneshaped wire coil, then'plao ing a wire lengthwise through the coil and a second wire lengthwise at the outer side of the coil and finally twisting the latter two wires to cause the individual coils to take a spiralling position around the twisted wires.
